Generation X was once known as the slacker, alienated ''MTV generation,'' distinct from smug Boomers and coddled Millenials. Growing up with the rise of AIDS, divorce and computers, Gen Xers were also once part of a hot youth movement fueled by grunge.

Two decades later, the average Gen Xer is now a middle-aged 42-year-old, according to a recent study by the MetLife Mature Market Institute.

The study also found that most Xers have a stable, traditional life - kids, spouse, mortgage - similar to that of their parents in the early '90s.

If you're among the 50 million Gen Xers born between 1965 and 1976, you don't need a study to tell you how old you are. Click these photos instead and be thankful you don't dress this way anymore.
